A fundamental requirement of Freon modeling is that the same void fraction and spatial phase distribution will exist in the Freon model as in the steam/water system being simulated. It is shown that this requirement is satisfied by comparing flow regime transitions observed in high-pressure steam/water with transitions observed in the half-scale Freon four-rod test. It is also demonstrated through predictions of a two-fluid model for a one-half geometric scale factor that within each flow regime, a similar slip ratio (vapor-to-liquid-velocity ratio) exists for the Freon and water systems.
